FINAL FOUR

The England international said: "So this happened to our young goalkeeper @pontusdahlberg in training on Sunday morning!!! Took a knee to the forehead and genuinely wanted to just get up and walk it off[sic]."

It remains to be seen whether the courage displayed by Dahlberg will be enough to improve his opportunities at Watford.

Dahlberg has not been involved in a Premier League match-day squad this season, with Heurelho Gomes the chief back-up to Foster.

After moving to Vicarage Road on a five-and-a-half year deal last January he was loaned back to Goteborg for the rest of the 2017-18 campaign and has therefore not played a senior game since May.

The closest he has come to a Watford debut came when he was named on the bench for the Carabao Cup clashes with Reading and Tottenham, which they lost on penalties.

His displays for Goteborg saw him win his one and only international cap for Sweden in January but was left out of their World Cup squad and has since returned to learning his trade with the Under-21s.

Six other Watford players are also waiting for their first appearance of the season, including defender Miguel Britos, winger Adalberto Penaranda and midfielder Tom Cleverley, who is nursing an Achilles injury.

Though it is expected that the ex-Manchester United man will resume his Watford career this season after resuming training last week.
